Type Alias TupleTail<T>

TupleTail: T extends readonly [unknown, ...(infer Rest)] ? Rest : readonly []

Gets the tail (all elements except the first) of a tuple type.

Unlike ArrayTail from type-fest, this preserves the tuple structure as a readonly tuple rather than converting to an array type.

Type Parameters

T extends readonly unknown[]
The tuple type to get the tail of

Example

type Example = TupleTail<readonly [string, number, boolean]>; // readonly [number, boolean]
type Single = TupleTail<readonly [string]>; // readonly []
type Empty = TupleTail<readonly []>; // readonly []
